Review on 🌡️ Accurate Temperature Measurements with Thermco ACC550DIG Digital Thermometer by Brett Kolpack

The primary purpose of purchasing a NIST certified instrument is to ensure that it stays within the validity period of the certificate. I waited much longer than the expected delivery date just to get the NIST certificate which expired in February 2018. Why is!? Then he has the nerve to ask me to pay for re-certification! Clearly incorrect rotation in the warehouse or careless people - intentional exposure. Just not again. waste of my time.wt
